Hi Geoff, I have the software working thanks mate. Regards Dave.

Hi all, does anyone have this software you can send me please. My email is [email protected] I am running a Windows 7 OS laptop that I use for tuning only, This has Windows 7 - 64 bit. I have tried downloading the software over and over and I keep getting the following error. I would very much appreciate if someone can pass on the download. I forgot to mention I have loaded the USB software and works fine. Kind Regards Dave.

Hi Geoff, so in rear wheel drive mode the solenoid has 0% applied and at full locked up is set is at 100% . Just curious as I was looking at making a LSD display to indicate the split load rear to front EG :: 70% REAR, 30% FRONT. More accurate for the end user rather than having the back light dim and brighten as an indication as to where you maybe set at when the adjustment changed. Regards Dave.

Hi, ECU PIN 53 is the VSS input to the ECU and cluster. Cutting this wire I would say will disable the speedo itself. Regards Dave.

Hi, thanks for the reply Steven. Do you know what the relays are for. Regards Dave.

Hi all, I have tried doing a search but cant find any relavent info, only regarding GTR. I am trying to indentify the fuses in the fuse box on the drivers side of the dash. I am also trying to identify the 4 blue relays mounted around the fuse box, what they do and which relay is which. Or if someone can direct me to a power distribution schematic diagram. Thanks Regards Dave.

More lift = more air into the engine and more exhaust out. Engines are air pumps. The more oxygen you can get in, and mixed with the correct amount of fuel, the more horsepower you will make. Simple as that. It's duration that has the biggest effect on your engines charactoristics. You must establish what you want to do with your car before choosing camshafts. Drag racing, Drift,Circuit Racing, Street/Strip etc. Duration is the key word here. EG: 220deg duration @ 0.050 is a small camshaft that would work well in street applications. Useable power range normally 2500-3000 rpm to 6000 rpm. 300deg duration @ 0.050 is a cranky piece of gear, application Drag Racing. Useable power range normally 4000 - 5000 rpm to 9000 rpm. Above mentioned examples are NOT exact figures but are stated to give you an idea. You can have a camshaft/s with 9.5mm of lift and 220 deg duration for street. You can have a more aggresive camshaft/s ground with 9.5mm lift and 260 deg duration,this camshaft will make more horsepower but at a higher rpm. Camshaft selection also comes back to engine hardware. 11 mm lift 300 deg duration on an engine with stock internals and standard turbo charger is pointless. What do you want to do with your car,what is done to your engine. I have made 625 hp @ the wheels with a customers car using only Tomie Pon Cams, but had the engine and turbo charger to support such a figure. I know that if i want more horsepower with that combination i need more lift and duration and another set of springs. However this is a street car and the owner dosnt want to sacrifice drivability. So lift increase with no duration change = small/ marginal performance gain. Lift increase with duration increase = more gain in power.

When using high lift camshafts it's not only the valve float issue created by weak valve springs that you must consider. You must make sure , you dont have coil bind issues at full lift, you must have clearance between underside of retainer to valve stem seal and valve guide, you must have enough piston to vavle clearance. if using larger valves, with big lift,high duration camshafts make sure on overlap the inlet and exhaust valves dont touch each other. Lift is part of the equation, Duration is where you need to do your home work. Duration is what will be one of the most important need to know specs of choosing the right camshaft for your combination. The higher the duration the higher in the rpm range you will make power and the harder you will have to rev the engine. Lobe seperation is another critical issue. The closer the lobe seperation and the larger the duration the more valve overlap you will experience. Valve overlap is unavoidable. Reducing this in a turbocharged or supercharged application isnt. Its called correct camshaft selection or can be altered (reduced) through variable timing gears. Large duration camshafts also suffer from more valve reversion on overlap. Creating pulses back through the inlet side. Not so much a problem on a GTR with 6 throttle blades as there is not really an inlet manifold as such to have these pulsations effect anything. MAF sensor tuning can be a little trickier on FC with big duration camshafts,as far as idle and light throttle cruise is concerned,on engines with 1 throttle blade. I tune engines using MAP or MAP THROTTLE if GTR. ECU of choice Autronic.
